Abstract

To define the spectral domain of the Newton volume integral, the kernel of Newton’s integral, i.e., the reciprocal value of the spatial distance is expanded into a series of the Legendre polynomials. It can be done only if the condition of convergence is satisfied (Hobson 1931; Sternberg and Smith, 1952), so that the ratio of the geocentric radii of the computation and integration points has to be ≤ 1. Considering for the gravitational field generated by atmosphere and topography, the spectral domain of Newton’s volume integral is discussed. Based on a theoretical investigation the analytical formulae for the gravitational potential and attraction are then introduced.
